! first lady michelle obama and daughters sasha and malia rocked out with hundreds of kids from military families and washington-area public schools. the concert included katy perry, mindless behavior, usher and members of the cast of the fox series "glee." the concert continues a tradition started at the 2009 inauguration by honoring the nation's military families. president obama will have two swearing-ins: a public ceremony on monday and a private one tomorrow. we'll have more on the preparations for the big event coming up. >> there is a constant battle on who is right, who is wrong on the next edition of people behaving badly. (male announcer): now, here's stanley roberts who found people behaving badly.pay attention to the man >> walking away from the camera . let's stop the video right here. now the question is will the postal truck do the right thing and yield to the pedestrian lets roll the video. nope, and it wasn't like the driver was in a rush he parked a few feet away. the law states that a driver shall yield the right away to a pedestrian in a marked or unmarked crosswalk.
